Forza Motorsport 5: Racing Game of the Year Edition will release on Xbox One on July 22, Turn 10 has announced (via IGN). The game will reportedly cost £50 in the UK.
The re-release features all of the original game's content, along with 10 additional cars, the Top Gear car pack and 18 "next-generation tracks". Unfortunately, there's no explanation yet as to what the developer means by next-gen tracks.
(UPDATE: Turn 10 has clarified that the 18 tracks include the 15 tracks featured at launch, along with Road America, Long Beach and 1 unannounced track.)
Forza Motorsport 5 launched alongside Xbox One last November with upcoming spin-off Forza Horizon 2 due out this autumn. The first footage of Horizon 2 is expected to be released later today.
